A nurse is explaining the process of collecting sputum samples for tuberculosis (TB) testing to a client. Which instruction should the nurse provide to ensure an accurate sample?
"Collect sputum samples immediately after waking up in the morning."
"Rinse your mouth with water before collecting the sputum to ensure cleanliness."
"Avoid deep coughing when producing sputum samples."
"Collect sputum samples in any container you have available."
The Correct Answer is A
A) Correct. Sputum samples are often most concentrated with TB bacteria when collected in the morning, as they have had time to accumulate overnight.
B) Incorrect. Rinsing the mouth before collecting sputum may dilute the sample and reduce its accuracy.
C) Incorrect. Deep coughing is encouraged to obtain samples from the lower respiratory tract, where TB bacteria are more likely to be present.
D) Incorrect. Sputum samples should be collected in specific containers designed for this purpose to maintain sample integrity and avoid contamination.

Explanation
A) Incorrect. It is not recommended to skip doses, but if the client experiences side effects, they should inform their healthcare provider rather than discontinuing treatment without guidance.
B) Incorrect. TB treatment must be completed in its entirety, even if the client starts to feel better. Stopping treatment prematurely can lead to drug resistance and a relapse of the disease.
C) Correct. Taking medications consistently and for the full duration of treatment is crucial to cure TB and prevent drug resistance.
D) Incorrect. Medications for TB should not be shared with family members or others, as they need individualized treatment and evaluation.
Correct Answer is D
Explanation
A) Incorrect. While multiple medications may lead to symptom relief, the primary goal is to prevent drug resistance.
B) Incorrect. The duration of TB treatment is determined by the specific regimen and is not solely related to the number of medications.
C) Incorrect. Multiple medications in TB treatment may target different aspects of TB bacteria, but the primary purpose is to reduce the risk of drug resistance.
D) Correct. Using multiple medications in combination therapy makes it more difficult for TB bacteria to develop resistance to all drugs simultaneously, helping to prevent drug-resistant TB.
